My wife is a strict serious, dominant but loving woman

I am not complaining about my wife. She is a strict serious, dominant but loving woman and I love her, just like this. She is in charge at home, and when she feels it's needed, she uses to punish me by locking my cock into a plastic chastity device and I can assure you, that if you could have a look at her body, you would agree with me that this becomes a really tough punishment so I tend to behave just as she expects me to do. But sometimes I miss a bit more of sense of humor in her ways. This appealing picture was taken more than three weeks ago with my mobile phone behind her back as you can easily understand, I couldn't refrain myself to softly smack her bottom.

I promise it was just a joke! But she promptly shaped her up, and slapped my face with all her swing. Less than five minutes later, my penis was securely caged. I have not seen the key since then and by now my balls is her jeans colour. I am just thinking about deleting the picture form my mobile device. I cannot take the risk of her discovering it right now! I know she cannot be perfect, but ...OMG, a bit of sense of humor. Just a bit!
